TOOL-HOLDER.'

SPECIFICATION forming part of Letters Patent No. 617,573, dated January10, 1899. Application led January 18, 1898. Serial No. 667,109. (Nomodel.)

To @ZZ whom t may concern.-

Be it known that I, ENocH HUGHES, a citizen of the United States,residing at Akron, in the county of Summit and State of Ohio, haveinvented a new and useful Tool-Holder,

of which the following is a specification.

This invention relates to tool-holders which are principally designedfor use in connection with lathework, and has for its object to providea holder of this character which can be used with drill-presses,Shapers, and with boring and threading tools, one of the principalfeatures residing in the special construction which admits of the toolbeing raised or lowered without disturbing its parallel relation with agiven or normal position. When interchangeable heads or holders areprovided, a boring-tool can be substituted for a threadingtool, and viceversa, without altering either the length of the tool or the stem in thepost, and for heavy work the holders can be duplicated and placed uponopposite sides of the tool-post, so as to provide a double bearing forthe tool.

For a full understanding of the merits and advantages of the inventionreference is to be had to the accompanying drawings and the followingdescription.

The improvement is susceptible of various changes in the form,proportion, and the minor details of construction without departing fromthe principle or sacriiicing any of the advantages thereof, and to afull disclosure of the invention an adaptation thereof is shown in theaccompanying drawings, in which- Figure 1 is a front view of atool-holder constructed in accordance with this invention. Fig. 2 is aside elevation. Fig. 3 is a rear View. Fig. 4 is an end view. Fig. 5 isa view in elevation showing the holder in operative relation. Y

Corresponding and like parts are referred to in the followingdescription and indicated in the views of the drawings bythe samereference characters. y

The tool-holder consists of a body or stock l and clamps 2 and 3 atopposite ends thereof and in parallel relation. These clamps are in theform of longitudinally-split sleeves, having offstanding ears l, whichare apertured to receive clamp screws or bolts 5, by means of which theclamps are contracted, so as to grip the tool and the tool post or stem,as required. The clamps are of different diameters conformable to thesize of the parts to be received therein and are somewhat longer thanthe body or stock to provide an extended frictional surface to insure anon-slipping of the holder upon the tool-post or the tool within theholder after the clamps have been properly adjusted to insure a bindingof the parts gripped thereby. The clamps are extended at opposite ends,so as to lie in different transverse planes, thereby securing the bestarrangement and enabling the holder to be positioned and manipulatedmore advantageously.

The tool-post or its stem is represented at 6 and the tool at 7, andthese parts are inserted into the clamps from opposite ends, as clearlyindicated in Fig. 5. If it be required to change the position of thetool so as to elevate or lower it, the clamp 2 is loosened and thus beseen that the tool can be changed Without disturbing its parallelism toa normal or given position, which is of advantage in lathe and otherwork.

Having thus described the invention, what is claimed as new, and desiredto be secured by Letters Patent, is-

l. A tool-holder comprising a body having a pair of oppositely-disposedclamp-sleeves arranged longitudinally in parallel planes, andtransversely in different planes, and a separate clamping device foreach sleeve, whereby each sleeve may be clamped and unclampedindependently of the other, substantially as set forth.

2. A tool-holder comprising a body having formed integral therewith apair of oppositelydisposed longitudinally split clamp sleeves arrangedlongitudinally in parallel planes, and transversely in different planes,each sleeve being provided intermediate its ends my own I have heretoaffixed my signature in and et its edges with offset parallel ears, andthe presence of [W0 witnesses.

clamping-Screws engaging the ears of the sleeves whereby each sleeve maybe clamped and unelzunped independently of the other,

substantially as set forth.

In testimony that I claim the foregoing as ENOCII HUGHES.
